Fix ERR_SSL_VERSION_INTERFERENCE Error

There are a lot of SSL/TLS related errors on the Internet, and the ERR_SSL_VERSION_INTERFERENCE error is a recent addition to the list.

But what is “ERR_SSL INTERFERENCE?” It is an SSL/TLS certificate related error that is often encountered when browsing websites with browsers like Google Chrome or Firefox.

This error occurs when the client (Web navigator) and the web server cannot agree when it comes to agreeing to support the TLS version by mutual agreement.

In most cases, one party, either the browser or the server, supports TLS 1.3 and the other does not support it at all.

Now, if you are facing this error, you are either a website owner or a web user. In this post, we will cover the solution from both angles.

How to Fix ERR_SSL_VERSION_INTERFERENCE Warning in Chrome as a Site Owner

If you are a website owner and you see ERR_SSL_VERSION_INTERFERENCE in Chrome, it is most likely because:

• Somehow it has disabled support for all TLS versions except TLS 1.3;
• You are using an older version of TLS 1.3; or
• Your SSL/TLS certificate was installed incorrectly or has expired.

Either way, your first step should be to check your server configuration to make sure it is enabled to support TLS 1.2.

Many users may not have updated their browsers and are still running TLS 1.2 (which would cause the error message to appear).

And if this doesn't work, you should check your SSL certificate to make sure it is still valid and hasn't expired.

If you recently installed your certificate, please check that you did it correctly. You should also consider reinstalling it if nothing works.

What causes the ERR_SSL_VERSION_INTERFERENCE error in Chrome?

In most cases, the error can be traced back to certain settings in Google Chrome.

There may also be problems with the storage cache website data locally on your PC.

Some of the most common reasons why you may encounter the ERR_SSL_VERSION_INTERFERENCE error in Chrome are:

• Cache: Temporary data stored by Chrome conflicts with SSL settings.
• TLS 1.3: Transport Layer Security feature conflicts with SSL in Google Chrome.
• Antivirus: In an effort to protect your browsing experience, your third-party antivirus' web protection feature is interfering with SSL.
• Corrupted installation files: In certain cases, Chrome has incomplete or corrupted installation files.

Before proceeding with the solutions, you need to log in to the Administrator user account on your PC. Also, you need to make sure that you have an active and open Internet connection.

Basically, you need to use a private network without proxies or firewalls. This also means that you cannot use public WiFi networks to perform the following solutions.
